Definitions
- the invention relates to a dental kiln, according to the preamble of claim 1, and to a method for operating a dental kiln according to the preamble of claim 11.
- Ceramic dental materials are typically fired at precisely predetermined firing curves and with accurate firing parameters. The setting of these firing parameters and firing curves is made in advance.
- Such dental furnaces have long been known, for example, on the DE 4 119 483 C2 and the DE 19 825 866 C1 is referenced.
- the firing cycles are sometimes quite different and differ from their nature; a distinction is made between the oxidation brand, the wash firing, the dentin firing, the cutting firing and the glaze firing; For all of them, the firing parameters must be strictly adhered to according to the manufacturer's specifications for the corresponding material.
- there are numerous programs especially since a longer cycle time for the firing cycle must be estimated even at higher masses of the dental restoration parts, so that therefore the heating time and the cooling time is extended for very large dental restoration parts such as multi-unit bridges.
- Such programs are typically hard-coded in the dental oven and can be modified by the user to a very limited extent. Due to the large number of program assignments, the operation of the dental kiln becomes rather cumbersome, especially with different materials to be fired. The complexity increases when the combination of the various fires mentioned above is fixed.
- the invention has for its object to provide a dental kiln according to the preamble of claim 1, which allows an improved result just for the final appearance of the dental restoration and offers a lower dependence on the experience of the dental technician.
- an operating element is provided, which is basically independent of the setting of the programs in detail. This reduces the complexity of the operation, because it is not necessary to combine every possibility of designing the glaze firing with the individual firing programs.
- the requirements for aesthetics can thus be met in a simple manner, without the loss of quality would be feared, because both in terms of translucency and in terms of the strength of the dental restoration, the result is already fixed before the glaze firing.
- the setting is surprisingly simplified without sacrificing quality significantly.
- the presetting allows the simultaneous and proportional or substantially proportional adjustment of these two parameters in synchronism with one another, so that it is possible for the dental technician, for example, to increase or decrease the intensity of the glaze firing starting from a normal glaze firing setting of his choice, depending on whether he wants stronger or less reflective surfaces.
- the dental kiln is designed from the outset so that the glaze firing is offered depending on the previous fires only in an area that allows no damage to the dental restoration part.
- an increased operating safety can be achieved, but still allows a finer differentiation of the desired glaze firing or glaze firing in the range of uncritical for the particular dental restoration parameters.
- the allowable range for the temperature and duration parameter pairs of the glaze firing can be shifted to higher ranges. This is then predetermined by the control program of the dental kiln so that the dental technician receives a standardized specification from the outset within the gloss range desired by him.
- the mean of the default may be quoted as "100%" and the lower and higher values given as a percentage.
- Fig.1 a combined display and control device 10 of a dental kiln according to the invention is shown.
- the digital kiln has an unillustrated control device which, in response to the input of program parameters via a button P of the display and control device 10, enables the control of firing cycles for dental restoration parts located in the dental kiln.
- the display and burning device has a touch-sensitive screen 12, which has fields such as the keys 14, the touching each triggers a function.
- the keys 14 and the other controls are only symbolically deposited and by touching the ever desired function is performed.
- the screen 12 has a display panel 16, on which, depending on the running program, the continuous firing curve the ever existing temperature at each existing measuring points of the dental kiln, or even the solid burning time is shown.
- the program function P can be operated by means of auxiliary keys 18 and 20, whereby individually programs can be selected, but changes in parameters can also be made within the programs.
- the oven hood of the dental oven can be opened and closed, so as to allow free access to the dental restoration part or to close the oven and thus initiate the firing cycle.
- keys 26 and 28 are provided, which are numbered with stop and start and to allow, for example, the start or stop of a firing cycle.
- a key 30 is additionally provided which is assigned to a glaze firing function.
- the display and control device 10 is changed with respect to the presentation content, so that in accordance with Fig. 2 apparent image results.
- the display panel 16 then displays, for example, the currently existing temperature in the dental kiln.
- the key P and the associated auxiliary keys 18 and 20 are hidden and instead a slider 32 is displayed, which is assigned to the glaze firing mode and allows to set the intensity of the glaze firing.
- the slider 32 has a controller 34, which moves on a touch of the finger along the slider 32, so as to achieve the desired glaze firing in to adjust its intensity.
- the button 30, the slider 32 and the controller 34 together form a control element for the glaze firing.
- the slider 32 is provided in the illustrated embodiment with markers that should symbolize the possible adjustment range.
- the minimum mark is 50% and the rightmost mark is 150%, it being understood that any other values, for example in the range between 30% and 300%, may be implemented instead.
- the key 30 is tapped again and the glaze firing started.
- the glaze firing is carried out and the slider is darkened to make it clear that once the glaze firing is initiated no change in the set parameters is possible.
- start button 28 can also be actuated and the relevant function can be triggered.
- the marks M1, M2 and M4 correspond to the preferred positions of the controller 32 for the users M1, M2 and M4.
- the control device of the dental kiln assumes that it is the same dental restoration part. Its once determined and fixed mass and type can be so far introduced into the translucencies of the glaze firing mode, so that a default according to the now to the glaze firing underonnedem Dentalrestaurationsteil is feasible.
- the glaze firing is triggered when, after the dental kiln was open, it assumes a standard setting for the glaze firing, which of course can be changed via the slider 32.
- a control device 40 is shown schematically in FIG Fig. 1 entered.
